Load Handling Capabilities Of Double-Rod Double-Acting Hydraulic Cylinders

The Double-Rod Double-Acting Hydraulic Cylinder

Double-rod double-acting hydraulic cylinders are a type of hydraulic actuator that utilizes two piston rods to generate force in both directions. These cylinders are commonly used in various industrial applications where precise control and high load capacity are required.

Principles of Double-Rod Double-Acting Cylinder

Double-rod double-acting cylinders operate on the principle of hydraulic pressure acting on both sides of the piston to extend and retract the piston rod. This design allows for precise control of movement and force application in both directions.
